"Optical Network + wireless" cracking smart city

Jointly creating smart cities using optical networks and Wireless Networks

After entering the 12th Five-Year Plan, the State clearly proposed to accelerate the construction of broadband, integration, security, and ubiquitous next-generation national information infrastructure, and promote the in-depth integration of informatization and industrialization, the overall idea of promoting informatization in various economic and social fields. The concept of "smart city" also emerges.

"Fixed Network + mobile" is the main line of the operator's network construction and business development. In the process of smart city construction, the city's optical network and wireless city will play a more important role and will be quickly opened with the climax of Urban Informatization Construction. In the future, many "Mysteries" such as how to build networks, how to expand applications, and how to satisfy differentiated user needs will also be uncovered on the road of Urban Informatization development.

Technological evolution matches Industrial Development

Urban optical network is an urban optical fiber broadband network that integrates IP, broadband, and convergence. It has the characteristics of "openness, high speed, ubiquitous, and intelligent, it is the network basis for realizing "smart city. However, it is not a simple task to promote the construction of urban optical networks. It is necessary to push "Urban Optical Networks" into residential areas, streets, and buildings.

EPON and GPON are defined by the industry as two mainstream and most mature access technologies, both of which can meet the development needs of the current business. However, with the acceleration of broadband networks, the existing optical fiber bearer technology for information transmission will face great challenges. technological upgrades are the trend of the times, and the evolution of EPON and GPON to 10GPON will also speed up.

Technological evolution will actively cooperate with industrial development, while 10GPON will well match the broadband development plan of operators. In the future, as the business continues to innovate and bandwidth requirements are getting higher and higher, 40g or even G will also be followed up quickly to cooperate with industrial development.

Smart upgrade of wireless cities

Wireless cities are the only way to develop urban informatization. Wireless cities first emerged in the United States and rapidly spread around the world. Wi-Fi is one of the most important technologies. With the continuous development of technology, the integration of various wireless technologies in wireless cities has become a consensus. The most typical example is the "3G + WLAN" mode.

In 3G, China's three major operators also stressed the development of high-quality 3G networks as they continue to expand the 3G network. In terms of WLAN, with the impact of the rapid development of mobile Internet, operators feel the pressure on data traffic in the future and pay more and more attention to WLAN.

"3G + WLAN" is only one of the most important methods in wireless cities. However, as the network environment becomes more complex, more technologies will be involved. It is understood that, in its 12th Five-Year wireless city planning, Shanghai Mobile specifically mentioned that during the 12th Five-Year Plan, will strive to build a TD-LTE technology to lead, 2G, 3G, WLAN, 4G "four network collaboration" ubiquitous, integrated, smart wireless city, and eventually become a ubiquitous, three-dimensional wireless city World Network.

When a smart city is combined with a wireless city and integrated into a smart network with optical fiber, Wi-Fi, and 3G seamless coverage, the roads in the smart city will gradually evolve.
